Khaled Habash, who owns the Blue Lobster on Portland’s Commercial Street, said his mother, Dawn Habash, of Augusta, left for a trip last week.

“We have not heard from her since the earthquake," Khaled Habash said.

Dawn, a yoga instructor, is believed to be at a national park 30 miles north of Kathmandu, Khaled Habash said.

"Last time we spoke was April 17 right before she was headed out on this 10-day trip,” he said. “Communication on the trek is not really typical. Didn't expect to hear from her until she was done with the trek.”

Habash said no communication from the region is not unusual.

“The villages are really rural,” he said. “Once you’re in the countryside, the infrastructure is not fantastic. I’m hoping everything is fine and if she is fine; I'm sure communication is close to none."

Habash’s concern now is the landslides that are hindering rescue teams from reaching those remote villages.

"I'm really worried,” he said. “I'm really worried."

Dawn Habash was scheduled to fly out of Kathmandu on Wednesday, April 29. Khaled said if he does not hear from her after that he will be extremely concerned.

International aid organizations are looking for donations to help people in Nepal and neighboring countries affected by the earthquake.

Donations can be made online to the American Red Cross, UNICEF and the International Medical Corps.
